I hope you don't mind feedback here.
1. I did maybe 2 runs already, but I feel that the elites in the 2nd battle too overpowered right now. One of them applies 30 shield per turn, which is way too much when each character can only attack once per turn, and at most can only do 20-30 damage each time. Another heals, and basically, that battle doesn't offer any better rewards compared to the normal battle next to it when its only a decrease in money. How is anyone suppose to get through that battle with only a relic draft, 1 card draft, and 2 units, let alone RNG of what you draw into your hand if you don't get an attack, move, or defense card to begin with (I had way too many hands when was full of one type of card and none of either of the other types. How can you block 30-50 damage on a unit per turn when you can only play 1 defense card on them and they can only block 10?
2. The Poacher is basically almost the worse character of the game right now. The main reason is because he can only attack in melee range, when both battles I did had to spawn a range unit that attacks from up to 5 squares away and move away from the target. I couldn't even reach ranged enemies with the Poacher because he can only move once per turn, and for a tactics game with melee units, he should be able to move twice per turn when you can't even draw the special card to reset his movement since the starting deck only has 2 special cards in it out of a 20 card starting deck, and due to the deck getting bloated by the first boss (you are forced to take every card offered to you in this verison, meaning you'll end up with too much of one card type down the line), I don't need basic attacks I can't do because I didn't draw the card that does said action when the AI doesn't have to worry about this problem.
3. Trying actions to a deck is basically asking for RNG to agree with you to even draw the card you need. I had too many turns of drawing a hand of attack cards, defense cards, etc. and even the mechanic of discarding 3 cards to find the one you get isn't enough to cut it here when you have to manage 3 units total after battle 2 and each unit can only do each action per turn. As you units die off in battles, that's less actions the player can even do, and whoever gets the outnumbered advantage basically ends up winning, which usually is the AI since they don't have to worry about a deck of cards to do their actions compared to the player who can't do one action if they don't draw the card to do it.
I hope that feedback helps. The demo needs a lot of work, and also, there was a bug when I downloaded where all of the social media icons being at the top right corner of the screen block the closed button from being clickable when you open the agreement in options to accept your data collected or something, and I had to leave the game to get out of the screen since the ESC button doesn't work on that screen.
